It delivers the required heating output, ensures a reliable supply of domestic hot water and can be used for efﬁcient cooling through circuit reversal. • A ﬂow temperature of up to 75 °C is available for heating mode and DHW heating. Protection against legionella is ensured without the need for an electric auxiliary heater. • The heat pump can also be used to heat older buildings via radiators, as a ﬂow temperature of 55 °C can still be achieved, even when there is a heavy frost (-25 °C outside temperature).Convenience features • Very quiet operation due to encapsulated refrigerant circuit and acoustically isolated compres-sor. Contributing to the low sound power level are the modulating fans and the wide gaps between the evaporator ﬁns which reduce air resistance. • High DHW temperatures are assured without the need for electric backup, even in the winter; this is because the heat pump works with high ﬂow temperatures all year round. • The system can be integrated into a home network and controlled from a mobile device. For this, the on-site heat pump manager is combined with the Internet Service Gateway (ISG). With integral heat and electricity metering via refrigerant circuit data. • Mono energetic operation possible thanks to integral emergency/auxiliary heater. • The enamelled, corro-sion-protected metal casing in alpine white is made from hot-dip galvanised, powder coated sheet steel. Fan grille, recessed grips and cover are made from weatherproof and UV-resistant plastic in aluminium white.Efﬁciency • The refrigerant circuit works with the eco-friendly, futureproof refrigerant R454C. When combined with the optimally matched components, highly efﬁcient operation is possible all year round. This efﬁciency is helped by demand-dependent defrosting via circuit reversal and the heating of the condensate pan via the refrigerant circuit. • The hydrophilic coating of the fan nozzle prevents ice formation, meaning that an electric heater is not required.Installation • Integral anti-vibration mounts enable the heat pump to be connected directly to the heating system. • Simpliﬁed installation thanks to pivoting electrical connection panel. • Quick access to the condensate pan via cleaning aperture on the back of the casing.WPL-A 07 HK 230 Premium WPL-A 07 HK 230 PremiumPart number 200123 Specification Energy efficiency class, heat pump W35 A+++Energy efficiency class, heat pump W55 A+++Energy efficiency class, composite system (heat pump + controller) W35 A+++Energy efficiency class, composite system (heat pump + controller) W55 A+++Heating output at A7/W35 (EN 14511) kW 3.31Heating output at A2/W35 (EN 14511) kW 3.19Heating output at A-7/W35 (EN 14511) kW 4.97COP at A7/W35 (EN 14511) 5.42COP at A2/W35 (EN 14511) 4.60COP at A-7/W35 (EN 14511) 3.45Max. cooling capacity at A35/W7 kW 4.73Cooling capacity at A35/W18 partial load kW 3.37
